fix: mobile layout fixes, i18n coverage, and recipe share link

Mobile:
- Recipes search bar full-width on mobile instead of capped narrow
- Cook mode ingredients panel stacks above the step instead of
  squeezing it into a narrow column
- Version history Compare/Restore buttons wrap onto their own row
- Recipe edit ingredient fields wrap instead of forcing horizontal
  scroll on narrow viewports

i18n: translates remaining hardcoded strings across recipes
filter/sort, adapt-recipe and AI variations dialogs, the full
settings section (sidebar + 6 sub-pages + BYOK/model-prefs/
API-keys/webhooks managers), explore tab, collections (new/fork/
share dialogs), meal planning (planner, AI generation phases, new
shopping list, shared-plan view), photo import, recipe bulk-select
toolbar, and recipe action-button tooltips. Also fixes the recipes
page subtitle, which wasn't just unworded but missing its {count}
interpolation entirely — it always rendered as the bare word
"results" regardless of how many recipes existed.

Feature: adds a ShareRecipeButton that copies the public /r/{id}
link to the clipboard, with a notice when the recipe isn't Public
yet.
